ZF 5838.300.507 LUBRICATION TUBE | OEM Genuine Part

Overview

The ZF 5838.300.507 LUBRICATION TUBE is a critical fluid delivery component engineered for heavy-duty construction machinery transmissions. This OEM genuine part channels pressurized oil directly to the planetary gear sets and clutch packs within the transmission housing, ensuring consistent lubrication and thermal regulation under extreme loads. The SKU 5838.300.507 is precision-formed to maintain proper oil flow paths, preventing metal-to-metal contact during high-torque operations. Without this tube, the transmission’s internal components would rapidly overheat, leading to premature wear of adjacent assemblies such as the 5838109007 DIFFERENTIAL and the 2095209019 DIFFERENTIAL.

Symptoms of Failure

• Visible oil leaks near transmission housing: A cracked or corroded lubrication tube will drip oil, often pooling under the vehicle after shutdown. This is a common long-tail search query for “ZF transmission oil leak at tube connection.”
• Gear slipping under load: Insufficient oil delivery causes clutch packs to slip, particularly in lower gears. Operators may notice delayed engagement or erratic shifting during grading or digging operations.
• Elevated transmission temperature warnings: When the tube fails, oil flow to the 0750117075 TAPER ROLLER BEARING is compromised, generating excessive heat that triggers dashboard alarms.
• Metallic debris in oil filter: Starved bearings and gears shed metal particles, which accumulate in the filter. This symptom often accompanies a failing tube and indicates secondary damage to the 0631329086 SPRING PIN assemblies.

Technical Specifications

Compatibility

This lubrication tube is designed for ZF WG series powershift transmissions commonly used in construction machinery. It directly fits the following models: WG180, WG200, WG210, and WG240. These transmissions are found in wheel loaders, bulldozers, and graders from manufacturers such as Caterpillar, Komatsu, and Volvo. Always verify your transmission serial number before ordering. The tube interfaces with the main valve body and routes oil to the differential housing, where it works in conjunction with the 5838300682 DIFFERENTIAL AXLE and thrust washers like the 5838300817 THRUST WASHER.
